Compressed air engine provided with energy storage system

Abstract

The invention discloses a compressed air engine provided with an energy storage system. The compressed air engine is composed of an air compression and heat exchange system and a pressure reduction and expansion acting system. The air compression and heat exchange system is connected with a buffer air storage tank (7) of the pressure reduction and expansion acting system through a heat exchanger (5) of the air compression and heat exchange system. The air compression and heat exchange system stores heat energy generated in the process of preparing compressed air through an air compressor (1), and the heat energy serves as heat energy required by heat supplying equipment of an automobile. The pressure reduction and expansion acting system converts pressure energy generated in the process of preparing compressed air through the air compressor (1) into mechanical energy required by acting of the engine (11) through expansion, and the automobile is driven to travel through the mechanical energy. No fuel is consumed in the process, no pollutant is contained in discharged tail gas, and meanwhile part of low-temperature gas discharged by the engine serves as refrigeration energy required by refrigeration equipment (14) of the automobile. According to the compressed air engine, the power mechanical field is made to intersect with and be integrated with the aerothermodynamics field and the dynamics field; the compressed air engine is novel and ingenious in design and simple in structure; zero emission can be achieved in real sense; energy efficiency can be maximized; and application prospect is good.

Description

technical field [0001] The invention belongs to the technical field of pneumatic engines in power machinery, and in particular relates to a compressed air engine with an energy storage system, which can store energy and drive vehicles to run, and realize zero emission. Background technique [0002] With the rapid development of science and technology, high-tech brings a high degree of civilized enjoyment to the society, but it also brings a heavy burden, especially the increasingly serious environmental pollution and the increasingly scarce earth resources, which need to be resolved major problem. The use of compressed air as the power source of automobiles is a more superior power than steam power, fuel oil, gas power, oil-electric hybrid power, pure electric power and other new energy power. The range of energy collected by compressed air power vehicles is very large. It is vast, highly energy-saving and pollution-free, and its acquisition method is superior and convenien...
